70 LEPIDOPTERA. 



beyond the middle are two yellowish-white opposite spots, of which that 

 on the inner margin is rather posterior ; both are frequently excessively 

 indistinct; cilia, beyond a dark hinder marginal line, greyish -fuscous. 

 Posterior wings greyish fuscous, with paler cilia. 



The female is larger, expanding 5\ lines, and the fascia and spots are 

 more distinct. 



ELACHISTA GREGSONI, Stainton, n. sp. Bred by 

 Mr. C. S. Gregson from black-headed, greenish-grey larvae, 

 found in a species of Poa near Liverpool last March. 



It is closely allied to E. nigrella, but the larva is very 

 different, and in the female the two opposite spots are more 

 exactly opposite. 



Alis anticis ( $ ) nigrescentibus, fascia tenui ante medium, maculis 

 oppositis pone medium, apiceque ipso albidis, obsoletis ; ( $ alis anticis 

 nigris, basim versus dilutioribus, fascia ante medium fere recta, maculis 

 oppositis distinctissimis, fasciam alteram rectam fere formantibus). 

 Exp. al. 8$ lin. 



Head greyish fuscous. Face and palpi whitish. Antennas dark fus- 

 cous. Anterior wings blackish, with a slender whitish fascia before the 

 middle ; two opposite spots beyond the middle, and the extreme apex 

 whitish; these markings are, however, very indistinct; cilia, beyond 

 a dark hinder marginal line, pale grey. Posterior wings grey, with 

 paler cilia. 



The female has the anterior wings black, the basal portion only a little 

 paler; the first fascia nearly straight, and the opposite spots, which are 

 very distinct, almost form another straight fascia. 



LITHOCOLLETIS VACCINIELLA, Scott, n. sp. 

 The larva was discovered last May by Mr. Scott at Focha- 

 bers, Banffshire, and Mr. Weaver in Perthshire, mining 

 the underside of the leaves of Vaccinium Vitis Idcei, and 

 the perfect insect was bred the following month. It is a 

 brilliant species, reminding one of L. ponii/oliella and L. 

 Lantanella, but readily recognised by the total absence of 

 any white scales on the inner margin of the anterior wings, 

 between the base and the first dorsal spot.
